One thing to be aware of in total hip replacements and I don't think it has been mentioned so far, is the risk of Leg Length Discrepancy..
It is one of the stated risks on the consent form that you sign before the operation..
I have had 2 hip operations in 3 years on the same leg/hip.. 1st op was for a fractured acetabulum where I had an 'orif' procedure done; open reduction with internal fixation.. Basically a titanium plate put in with screws to secure a piece of the acetabulum that had been broken by the force of my rtc..
Recuperating from this op was v hard - could not put my leg on the floor for 5 weeks really, then a max of 7kg weight on it for 3 months I think before fully weight bearing.
After nearly a year where walking was still awkward it was determined that I would need a total hip replacement, which I had on 29/01/20..
Luckily this went well and I was discharged the next day after the operation. I was at home 24 hours when I realised that my undamaged leg was straight yet my damaged leg had a slight bend to it. Then it came back to me about the consent form, stated risks etc.. I never thought I would actually end up with a LLD .. I was pretty fed up for the whole week end till I realised that the main thing is I had a stable and pain free hip joint.
I ended up with the operated leg being approx. (not been properly measured so far), 9 - 12mm longer than the other leg. I wear an insert in the other shoe to even things up as I found it odd walking, as if I had one shoe on and the other off. Many (un-operated),people are walking around with a LLD without realising but if you never had one before it is quite obvious..
Good thing is now I'm back on my push bike, my leg strength has gone up massively although the muscles on the affected leg still look a bit skinnier than the other leg.
The surgeons make every effort to make the replacement hip the same length as the other leg/hip - but the risk of a LLD is increased I think if you have been walking around on a damaged hip for a long time. A colleagues MIL ended up with one leg 2 inches shorter than the other as her hip was very badly worn.
good luck OP but it's a great operation if all successful and the recovery is literally a walk in the park compared to the first procedure that I had..
